Removed distinction between "available" and "init" in audio backends, since
both had to be checked for success as a pair at the higher level and several
of the Available methods were just always-succeed placeholders anyhow. Now
the availability check is done in the init code, and the higher level tries
all possible drivers until one manages to initialize successfully.
